Serial Nor 203,708.

My inventionrelates to a combined knob or latch adapted for use in connection with cupboards, drawers and the like, and especiallywhere it is desired that the knob associated therewith will be of ornamental appearance, and at the same time the unlatching of said knob by said latch may be accomplished by the natural movement induced by turning said knob either clockwise or counter-clockwise, which movement is independent of the action of the latch when the door or drawer with which it is associated is closed.

It accordingly is an object of my invention to provide a novel form of combined knob and latch device having a pair of sleeves adapted to coact with each other so that the device may be secured to a support, one or both of said sleeves having means associated therewith whereby said sleeves may be firmly secured to said support, a preferably ornamental knob being positioned in one of said sleeves and adapted to operate a latch in pivotal association with one of said sleeves by a turning movement of said knob, said latch havlng means for engaging a keeper, said turning movement functioning to release the keeper from the latch, but at the same time permitting an independent vertical movement of the latch for engaging said keeper.

The above and further objects and advantages of my invention, as will hereinafter more fully appear, I attain by the device constructed in accordance with the description thereof and illustrated on the drawings forming a part of my application.

Reference is had to the accompanying drawings, in which similar reference characters denote similar parts. In the drawings,

F ig; 1 is a longitudinal sectional view of my device illustrating its association with a support, the latch being shown in engagement with its keeper,

Fig. 2 is an exploded view of the parts of my device with sleeves omitted, which parts are shown in side elevation,

Fig. 3 is a fragmentary side elevation of a slight modification illustrating a wrench engaging means for securing the device to a su ort PP F ta 4 is an elevational view of Fig. 3,

Fig. 5 is a side elevational view of a modification in which one of the securing sleeves is in direct alignment with the other,

Fig. 6 is a somewhat enlarged elevational view of the cam means, and Fig. 7 is a top plan view of the latch. Describing my invention more in detail,

the device as shown in Figs. 1 and 2, coma prises a pair of sleeves 2 and 4, the sleeve-2 being externally threaded as shown [to en gage with the internal threads of the sleeve 4, said sleeves being adapted to be positioned within the hole 6 in thedrawer or door 8-.of the cupboard or other device, 10 which is equipped with any preferred form ofkeeper.

12, secured thereto by any suitable means as the screws 14. f 1

The keeper 14: is adapted to be engaged by the hook 16of the latch 18, whichla'tch may be in the form of a flattened elongated member,-bent or warped as at 20, and provided with a suitable pivot holding portion 22,

bored as indicated at24r. (Fig.7) to house the pivot pin 26, which pivot pin extends through and is anchored in thesleeve 2. The latch 18 is alsoprovide'd with a preferably fiat portion 28, cut'as shown in Fig. 7 to provide a means adapted to be engaged by the cam means 30, presently to be more partic ularly described. It will, of course, be understood that the shape and specific construction of the parts 22 and 28 is immaterial and may in practice be Changed. I v

Associated with'the latch 18, 'andiprefen ably surrounding the pivot pin 26 is a coiled spring 32, which spring has itsends'in engagement with the latch 18 and the sleeve 2, so that any turning movement of said latch may be resisted, said latch when turned in either a clockwise or counter clockwise direction by the means presently to be described, will be returned to its original position by said spring. It will also be (clear that any other means of mounting said spring may be substituted for that shown and described still remain withi the province of myinvention. j I i The mean or ope a ing he la ch 1 .5 S

structed of glass or other suitable material, I 7 said knob having its vbase 38 firmly secured in a base 3 L, preferably spun over the base 38 or secured-thereon in any other preferred Preferably i'ntegral with the base 345 is an extension'Oqwhi'ch is adapted to fit rather snugly Within the thickened portion 42 of the" sleeve yetwithal without binding, so that r saidextensionmay be turned therein, and;

' Within the extension 40 is positioned a headed rivet or other member 44, wvhich: may be threaded to said extension asshown, and its,

7 head in close engagement 'with the base 36,; ;Tothe rivet 44 issecured the cam means 30, either 3 threaded thereonor associated therewithi'n any other desired mannensaid.

V cam'means being provided with a projection 1 or ent-away portion 46,"vvhichprojection is 2 adapted to engage the flat portion 28 'ofthe latch 18 soithat'when the' knob 36 is turned either in fcl'ockwise oracounter clockwise'dr' rection the latch will be released" from j the -keeper12, against the action'of the spring 32, aaivhichspring Will return' saidlatchgto its original position when the'knob 36 is released. 1 h The sleeve 2 may; be provided with a' I rounded portion't8 tobe engagedby apair of p'lier s sothat said sleeve maybe screwed- 30 home withinthe supp'ortS', or said portion may take the form of ahexagonal or other ,nut 4L8 asseen in Figs. 3 and L'fOre'ngagehave a-suitably'shaped flange 50ito be en- ;gaged by a pair of pliers or awrenchl It will be clear also that the usu alconventional form of washersniay be provided.
